this was from mt tech.

On the road you will need around 32 psi at the strip run 12-16 psi.

those two pages contradict each other. i ran mine at 16 (315 radials) and the didnt hook well at all, but they werent broken in yet, so that isnt a good indicator.

last time they stuck much better. i ran them at 18, then at 17. not much difference in 1 pound, but i wanted to keep the variables down and just work on my launch technique.

since that one bulletin says that the 295 and above radials should be ran at 11-14psi on 3000lb cars and above, i think next time i go out i may try and run those bitches at 12 and see what happens. i honestly dont see it being any better since the sidewall isnt really going to give regardless of the psi, and in getting a lot of contact patch at 17-18 psi...

oh yeah, best 60' to date is a 2.11. either bog a bit, or spin a bit.....

what is the difference in the ET drag radial and the ET? ive never seen an MT ET Radial that isnt the "Street".

i was comparing the instructions for the ET radial on the first page vs. the ET "street" radial....

well i just looked them up. ive never seen those before.

but does 11-14psi on my 315/35 17 street radials sound right?

i think thats way too low.....if anyone else has tried it, lemme know.

that sounds right. my problem is that im an M6

here are some pics after running 17-18 psi.

i dont think anything less would help me any, because im getting a wide contact patch.

you can see where the contact is when im running 32psi on the street, and also where its contacting when im running 17-18psi....

32psi is too much for the street. Youll wear out the centers quiicker

18 to 22 is a much better choice if you want them to last

the MT tech page says to run them at 75% of the max psi posted on the side wall....

max psi is 44. 75% of that is 33psi.....

i may drop them down to about 26-28 though. just enough to get more contact patch on the tread....
